80064 Midland Liquid-Filled Pressure Gauge, 0–100 PSI, 2-1/2 in, Lower Mount

For equipment that needs 0 to 100 PSI indication, the 80064 uses a liquid-filled Midland gauge body, a 2-1/2 in dial, and a 1/4 in NPT connection at the lower mount.

For a 100 PSI requirement with a lower connection, this SKU keeps the pressure scale tightly matched to that operating window. Choose this range when the equipment normally stays within a lower-pressure operating window and a broader high-pressure scale would sacrifice readability. Its 2-1/2 in format is a versatile middle size in Midland's liquid-filled lineup, suited to many equipment layouts.

Midland specifies a stainless steel case, copper-alloy wetted parts, and a polycarbonate window, along with ±1.5% of span accuracy and a -104°F to 158°F temperature range. Because the gauge is glycerin filled, it is better suited to vibrating or pulsating service than a comparable dry gauge; the fill also lubricates the movement.

For replacement or new installation work, verify the range and mounting position first, then confirm the connection and construction in the specifications below.
